The phrase 'low-carbon concrete' has entered the lexicon over the last few years, part of an overall move in all areas of the construction industries to produce less carbon-intensive materials and also to lower the carbon output of the construction processes themselves. A major part of this is all aspects of concrete, because it …

Start-up hopes to eliminate carbon emissions from global cement market 04:24. Cement is the most widely-used substance on Earth after water. When mixed with water, it forms concrete that becomes ...

The total volume of cement production worldwide amounted to an estimated 4.1 billion tons in 2023. Back in 1995, the total global production of cement amounted to just 1.39 billion tons, an...

India strengthened its position as the second largest cement producer in 2022, with the country's share of global production rising from 8% in 2021 to 9%. Over the longer-term, declining production in China is expected to be offset by production increases in Southeast Asia, Latin America and Africa to meet their development needs.

In 2021, the world's leading producers, representing 80% of global production outside of China, became the first 'heavy' industry to set out a clear pathway to decarbonisation, by signing up to the GCCA's Cement and Concrete Industry's 2050 Net Zero Roadmap and committing to help limit global warming to 1.5C, in line with UN …

The top five cement producing countries (China, India, Vietnam, United States and Indonesia) account for approximately 68.2% of global cement production in 2020, with China alone accounting for ...

Production of cement, the key ingredient in concrete, accounts for around 7% of global CO 2 emissions. The new 2030 commitment by the GCCA outlines a significant acceleration in the pace of ...

Launched by the Global Cement and Concrete Association (GCCA) on behalf of its member companies, the ambition statement represents a critical milestone for the industry. It is the first time it has come together globally to state a collective ambition for a carbon neutral future. The statement identifies the essential levers that will be ...

The global cement and concrete demand, production, supply, and the general global market price was modelled using the WORLD7 model for different future scenarios. The model was used to analyze some possible measures to reduce the climate impact of cement production. The main result from this study is that three factors may …

The results show that concrete production was responsible for 9% of global industrial water withdrawals in 2012 (this is approximately 1.7% of total global water withdrawal). In 2050, 75% of the ...

The Global Concrete Report - 2023 is an updated overview of the global concrete industry. The report lists the 0 concrete-producing countries and the largest 40 global concrete companies. The report was developed usi...

The cement and concrete industry has established new targets to lower and even eliminate emissions, such as those set by the Global Cement and Concrete Association (GCCA). These targets aim for a 20 percent reduction of CO2 per metric ton of cement and a 25 percent reduction of CO2 per cubic meter of concrete by 2030 …

A projection of global emissions from production of cement-based materials between 2015–2100 was modeled based on projected per capita saturation levels, projected population, and average in-use service lives of cement for 10 global regions. The model used was initially developed by Cao et al. 24.

The production of cement clinker in the U.S. reached about 77 million metric tons in 2023. Overall, U.S. cement production remains under the 2005 record due to idle production plants ...

As …

Worldwide every year cement and concrete production generates as much as 9 percent of all human CO 2 emissions. Societies have made cement and concrete in pretty much the same way for a century.

Concrete production contributes to 8% of global anthropogenic greenhouse gas emissions and consequently, is a target industry to decarbonize to limit global warming by 2050. Our study presents near-term strategies to significantly reduce greenhouse gas emissions from concrete production globally.

Emissions intensity of cement production has risen by nearly 10% since 2015, largely due to an increase in the clinker-to-cement ratio in China. By 2030, total emissions need to fall by around 20%, enabled in part by an increase in CCUS. During the 2020s, costs of producing near-zero emission cement are likely to remain significantly higher ...
